<p>Apparatus and methods for actuating rotatable members are disclosed. In one embodiment, an assembly (60) for actuating a rotatable member (22) includes an extendible actuator (24) having a first end (30) and a second end (40), and a drive member (74) having a first portion (72) pivotally coupled to the second end (40), and a second portion (76) non-pivotally coupled to the rotatable member (22). The second portion (76) of the drive member (74) is spaced apart from the first portion (72). The drive member (74) further includes a third portion (78) spaced apart from the first and second portions (72,76) in a non-linear orientation. The assembly further includes a reaction link (90) having an anchoring end (94) pivotally coupled to the first end of the extendible actuator, and a driving end (92) pivotally coupled to the third portion (78) of the drive member (74). <IMAGE></p> |
