The retainer includes a retainer body and at least one cam rotatably secured to the retainer. The valve stem connector assembly further includes a retainer latch coupled to the lead screw and the retainer. The retainer latch is configured to move from a normally unlocked position in which the valve stem is unsecured from the lead screw and a locked position in which the retainer latch moves toward the retainer to rotate the at least one cam to secure the valve stem to the lead screw. A method of releasably securing a valve stem of a globe valve to a lead screw of a globe valve actuator is further disclosed.
