Claim Text:
1. A rotating control system, comprising: a member having at least one clevis defined by a pair of clevis arms having a pair of aligned holes; a spherical bearing disposed between the pair of clevis arms and having a through hole aligned with the clevis arm holes; a connecting in extending through the spherical bearing through hole and the clevis arm holes; a shaft member comprising an actuator rod and a bearing housing disposed at an end of the actuator rod and having a through hole defining a cavity pivotally receiving the spherical bearing between the pair of clevis arms, the shaft member having a rod axis concentrically extending along the actuator rod and a pivot axis concentrically extending through the bearing housing cavity; and an anti-rotation device for limiting a rotation of the shaft member about the rod axis, the anti-rotation device comprising a multi-piece clip having two clip members which are symmetrical about a plane containing the rod axis and the pivot axis, each clip member comprising: a collar portion configured to wrap around a portion of the actuator rod; a ring portion defining a cavity configured to wrap around a portion of the bearing housing and concentric with the pivot axis; and at least one restraining member that extends from a side of the ring portion toward the clevis arms for limiting the rotation of the shaft member about the rod axis, and wherein the at least one restraining member has an inner surface having a concave spherical shape for receiving the spherical bearing and an outer surface having a bulbous shape relative to the plane of symmetry of the clip members; wherein the clip members have a plurality of aligned apertures for coupling the clip members around the shaft member; and wherein at least one aperture is located at an apex of the anti-rotation device.
