Abstract
A universal coupler for a self aligning linear actuator for a valve assembly. The self aligning linear actuator utilizes a drive screw or other threaded drive means to drive a plunger for a throttle valve. The drive screw rotates within a frame while a threaded collar or ball screw coupled to a drive coupler drives the plunger parallel to the drive screw. The universal coupler relieves any bending strain induced by misalignment between the drive screw and the plunger by allowing pivotal movement of the drive coupler relative to the drive screw.
