A rotary actuator (18) is provided, including an actuator assembly (20). The actuator assembly includes a torque tube (24) formed of a shape memory alloy, a super elastic NiTinol return spring (26) having a proximal end (46) and a distal end (44), and a torque tube heating element (30) positioned near the torque tube. The torque tube (24) includes a proximal end (32) and a distal end (34). The return spring and torque tube are connected at their ends, with the torque tube being pretwisted while in a martensitic state relative to the spring. Activation of...
