Abstract: Example apparatus include load relieving stem connectors. An example apparatus includes a connector housing including an internal cavity therein, a load relieving body disposed in the internal cavity, and a shaft coupled to the load relieving body. In the example apparatus, the shaft is to rotate the load relieving body between a first position and a second position.

Abstract: Apparatus for operatively connecting an actuator rod to a valve stem is disclosed. An example apparatus includes a connector housing having an outer surface and an inner surface where the inner surface defines an internal cavity. The example apparatus also includes an actuator rod passage extending from the outer surface into the internal cavity that is adapted to receive at least a portion of the actuator rod and a valve stem passage extending from the outer surface into the internal cavity that is adapted to receive at least a portion of the valve stem. Additionally, the example apparatus includes a load relieving body disposed within the internal cavity between the actuator rod passage and the valve stem passage.

Abstract: Collets for coupling rotary actuators to process control devices are disclosed. An example collet includes at least one flexible member having a first surface 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. The flexible member is coupled to a first end of an elongated member and configured to be displaced toward an axis of the elongated member by the third surface. The elongated member is configured to be coupled to at least a portion of a process control device actuator.

Abstract: An example anti-rotation apparatus includes a first member configured to be disposed within an aperture of an internally threaded component. The first member includes a first end having a recessed portion configured to receive a second member disposed within the aperture of the internally threaded component. The recessed portion of the first member is configured to receive the second member to cause a peripheral portion of the first end of the first member to frictionally engage a surface within the aperture of the internally threaded component.
