A wedge lock assembly, comprising: a plurality of wedge members (110a, 110b, 111a-e, 112a-d) arranged adjacent to one another along a longitudinal axis, the plurality of wedge members including end wedge members (110a, 110b) at opposite ends of the plurality of wedge members, and one or more intermediate wedge members (111a-e, 112a-d) between the end wedge members; a displacement device comprising a screw extending along and rotatable about the longitudinal axis and connecting the end wedge members, the displacement device actuatable in one direction to move the end wedge members toward one another to displace adjacent wedge members relative to one another in a direction transverse to the longitudinal axis to engage and apply a clamping force to two components (101, 104) external to the wedge lock assembly; and a variable gap compensation mechanism comprising: a spring associated with the screw and operable to exert a biasing force on the plurality of wedge members to accommodate the relative transverse movement of the adjacent wedge members and maintain the clamping force on the two components by the plurality of wedge members within a predetermined range as a distance between the two components varies; and a spring retainer associated with the screw and the spring, such that rotation of the screw moves the spring retainer relative to the screw to preload the spring and apply the clamping force to the two components, the retainer being prevented from rotating with the screw by a pin coupled to the retainer and extending at least partially into a slot, and further comprising a spring preload position indicator proximate the slot, the pin being visible through the slot relative to the spring preload position indicator to indicate whether the spring is preloaded sufficient to apply the clamping force on the two components. a plurality of wedge members (110a, 110b, 111a-e, 112a-d) arranged adjacent to one another along a longitudinal axis, the plurality of wedge members including end wedge members (110a, 110b) at opposite ends of the plurality of wedge members, and one or more intermediate wedge members (111a-e, 112a-d) between the end wedge members; a displacement device comprising a screw extending along and rotatable about the longitudinal axis and connecting the end wedge members, the displacement device actuatable in one direction to move the end wedge members toward one another to displace adjacent wedge members relative to one another in a direction transverse to the longitudinal axis to engage and apply a clamping force to two components (101, 104) external to the wedge lock assembly; and a variable gap compensation mechanism comprising: a spring associated with the screw and operable to exert a biasing force on the plurality of wedge members to accommodate the relative transverse movement of the adjacent wedge members and maintain the clamping force on the two components by the plurality of wedge members within a predetermined range as a distance between the two components varies; and a spring retainer associated with the screw and the spring, such that rotation of the screw moves the spring retainer relative to the screw to preload the spring and apply the clamping force to the two components, the retainer being prevented from rotating with the screw by a pin coupled to the retainer and extending at least partially into a slot, and further comprising a spring preload position indicator proximate the slot, the pin being visible through the slot relative to the spring preload position indicator to indicate whether the spring is preloaded sufficient to apply the clamping force on the two components. a spring associated with the screw and operable to exert a biasing force on the plurality of wedge members to accommodate the relative transverse movement of the adjacent wedge members and maintain the clamping force on the two components by the plurality of wedge members within a predetermined range as a distance between the two components varies; and a spring retainer associated with the screw and the spring, such that rotation of the screw moves the spring retainer relative to the screw to preload the spring and apply the clamping force to the two components, the retainer being prevented from rotating with the screw by a pin coupled to the retainer and extending at least partially into a slot, and further comprising a spring preload position indicator proximate the slot, the pin being visible through the slot relative to the spring preload position indicator to indicate whether the spring is preloaded sufficient to apply the clamping force on the two components.
