Abstract

An actuator for use in a control valve assembly that has a structure amenable to manufacture. The actuator may comprise a housing comprising a plurality of walls secured to one another with fasteners to form an interior cavity, a torque hub disposed in the interior cavity, the torque hub comprising a torque body and a torque arm that are releasably engaged with one another via fasteners, each of the torque body and the torque arm having interfacing geometry that defines surfaces that engage with opposing surfaces on the other; and a load generator coupled with the torque hub.
