A coaxial hydraulic actuator system utilizes a vane pump close coupled to a vane actuator. The vane pump includes a rotatable housing which is perpendicularly movable by a control piston to direct fluid flow through first and second fluid conduits in a pintle port transfer shaft. The transfer shaft conduits are in communication with first and second variable volume compartments in the vane actuator. Thus, controlled movement of the vane pump housing results in corresponding resulting angular movement between the actuator vane and the actuator housing. This relative angular positioning can be used to control the relative positioning between first and second loads, such as the rotors of a dual permanent magnet generator.
