Abstract: An actuator assembly with integrated torque turn monitoring is described. Embodiments include a rotationally fixed outer hydraulic section and a rotationally independent inner hydraulic section which incorporates torque load sensors, axial load sensors, and rotational speed sensors directly into the inner hydraulic section. The inner hydraulic section is coupled to an outer cage by a cage ring and is axially movable relative to the inner mandrel. Upper and lower fluid chambers are disposed between the outer housing assembly and the inner mandrel. Fluid pumped through a lower pressure port into the lower chamber moves the housing assembly in a first direction, and fluid pumped through an upper pressure port into the upper fluid chamber moves the housing assembly in a second direction.
