Abstract: A valve actuator assembly that include an actuator and an actuator mounting assembly. The actuator mounting assembly may be secured to a valve shaft without the actuator present, and the actuator may be secured to the actuator mounting assembly later. This can make it easier to mount the actuator mounting assembly, especially in cramped spaces. In some cases, the actuator may be wired where it is convenient, and then moved to the actuator mounting assembly and secured to the mounted actuator mounting assembly, sometimes with a simple snap attachment. In some cases, a button, lever or other mechanism may release the actuator from the actuator mounting assembly for easy removal.

Abstract: A self-centering shaft adapter may include a first jaw, a second jaw, and an actuation mechanism, wherein the first jaw and the second jaw define an opening for receiving a shaft therein. The actuation mechanism may be able to exert a force upon the first jaw and the second jaw creating a movement in the first jaw and the second jaw in opposite directions. The movement of the first jaw and the second jaw may increase or decrease the size of the opening. In some cases, the opening may maintain a relatively constant center regardless of the size of the opening. In some cases, the actuation mechanism may be a wedge. In other cases, the actuation mechanism may be a double-threaded screw.
