Abstract
Apparatus for close positive coupling of an actuator to a ball valve utilizes a bracket plate assembly fixing the valve and actuator bodies together and supporting the hexagonal alignment bushing in fitted engagement with the valve stem gland screw to apply reactive loads generated by valve actuation forces to the gland screw rather than the valve stem, whereby essentially only torsional actuation forces are applied to the valve stem.
