Abstract: The present disclosure generally relates to an external shaft connection assembly. In particular, an external shaft connection assembly for use with vane actuators is disclosed. In various aspects, the disclosed assembly includes an external shaft connector to connect a valve to the vane actuator, an upper shaft to connect a positioner the vain actuator and a compression ferrule to ensure a tight fit with the vane actuator in order to overcome mechanical slop and inefficiencies in motion transmission due to variances in manufacturing tolerances.
