COLLETS FOR USE WITH PROCESS CONTROL DEVICES

摘要

Collets for coupling rotary actuators to process control devices are disclosed. An example collet (202) includes at least one flexible member having a first surface (302) and a second surface. The first surface is configured to engage a rectangular shaft and the second surface is configured to engage a third surface of a substantially rectangular bore (304). The flexible member is coupled to a first end of an elongated member (308) and configured to be displaced toward an axis of the elongated member (308) by the third surface. The elongated member is configured to be coupled to at least a portion of a process control device actuator.
