Claim:
1. An apparatus for use with a control valve actuator, the apparatus comprising: a rod end bearing having a bearing retainer and a shaft portion extending from the bearing retainer, the shaft portion defining a first face and a first bore; and an actuator stem having a first end to be operatively coupled to a diaphragm plate of the control valve actuator and a second end to be coupled to the rod end bearing, the second end defining a second face and a second bore, the first face and the second face include complementary-shaped portions that interlock when the first face is in engagement with the second face to provide a lock that prevents rotation of the actuator stem relative to the rod end bearing when the actuator stem is rotated in a first direction, the first bore to be coaxially aligned with the second bore when the first face is in engagement with the second face.
