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 with the bracket plate in fitted engagement with the valve body annularly about its valve stem gland screw to apply reactive loads generated by valve actuation forces to the valve body rather than the valve stem, whereby essentially only torsional actuation forces are applied to the valve stem. The bracket plate assembly is affixed to the valve and actuator bodies, respectively, at opposite axial sides of the gland screw drive periphery for easy tightening access thereto without disassembly of the bracket assembly.
