Manufacture of actuators and control valve assemblies

An apparatus, comprising:

• a hollow enclosure having a front, a back, a top, and a bottom;
• a spring-loaded actuator disposed on the top of the hollow enclosure, the spring-loaded actuator having a connecting rod that extends into the hollow enclosure;
• a torque hub having a first end coupled with the connecting rod, the torque hub having a cylinder set off from the first end,
• wherein the cylinder is accessible from the back of the hollow enclosure.

A method for actuating a valve, comprising:

• receiving a load from a pneumatic actuator on a first joint formed by a pair of plates;
• directing the load to a cylinder via interfacing geometry that defines surfaces that engage with opposing surfaces on the pair of plates, the surfaces found on an outer surface of the cylinder and on an inner surface of an aperture that penetrates both of the pair of plates and that receives the cylinder therein;
• and
• using the load to rotate a shaft of a valve that couples with the cylinder.
