Claim:
1. An apparatus, comprising: a center spindle extending along a longitudinal axis in a proximal direction and a distal direction, the center spindle comprising a cup including a longitudinal center spindle slot; an outer spindle comprising a longitudinal outer spindle slot; and a lock control assembly configured to selectively couple the center spindle and the outer spindle, the lock control assembly comprising: wherein the lock control assembly is operable in a locking state and an unlocking state; wherein, in the locking state, the follower surface distal level is in contact with the cam surface proximal level, the locking bar is in the locking position, and the outer spindle is rotationally decoupled from the center spindle; wherein, in the unlocking state, the follower surface distal level is positioned distally of the cam surface proximal level, the follower surface ramp is positioned adjacent the cam surface ramp, the locking bar is in the unlocking position, and the outer spindle is rotationally coupled with the center spindle; wherein the proximal side of the cam follower includes a positioning surface comprising a positioning surface proximal level and a positioning surface ramp extending distally from the positioning surface proximal level; wherein the cam follower further comprises a proximally extending stop positioned adjacent the positioning surface proximal level; and wherein, in the locking state, the locking bar is positioned in contact with the positioning surface proximal level, and the stop is positioned adjacent the arm.
