Patent ID: 7509971

Claim:
A fluid valve assembly, comprising: a valve from which extends a movable valve stem for controlling fluid flow through the fluid valve; a mounting plate having an axially projecting open-ended hub positioned around the stem and having a flange with at least one axially extending wall; a seal plate to which the valve is mounted having an aperture receiving the hub of the mounting plate and including a flange having at least one axially extending wall at least a portion of which is positionable in spaced relation with respect to the wall of the mounting plate to allow the position of the seal plate to be adjusted relative to the mounting plate; and a rotatable handle linked to the hub of the mounting plate to rotate about an axis of rotation that it is fixed essentially concentric with respect to the hub of the mounting plate and relatively adjustable with respect to the seal plate; wherein the handle is linked to the valve stem through a flexible coupling device, which includes a stem adaptor linked to the valve stem and a stem driver linked to the handle, wherein at least one of the stem adapter and the stem driver comprises a plurality of slots and the other of the stem adapter and the stem driver comprises a plurality of projections sized and dimensioned to be received in the slots, whereby the flexible coupling device can transfer torque between the handle and the stem to open and close the valve even when the handle and stem are rotating on different axis axes.
