ABSTRACT:
A rectangular cavity is provided in an actuator lever intersecting with an upper edge of a shaft-receiving hole in the lever and receives a linearly slidable hard metal rectangular key having a cam on one edge for clamping the lever to the shaft. A screw engages threads on the key and is slidable with the key to a position where a distal end of the key is flush with or projects from a side surface of the lever, at which position the cam is free of the shaft-receiving opening, the key providing visual indication that the lever assembly may be positioned over the shaft without interference.
