An actuator assembly (10) may comprise a housing (12), a shaft (62), a shape memory alloy (SMA) torque tube (18), and first and second unidirectional bearings (32,36). The SMA torque tube (18) may rotate the shaft (62). The first unidirectional bearing (32) may limit rotation of the shaft (62) relative to the SMA torque tube (18) to a first direction. The second unidirectional bearing (36) may prevent rotation of the shaft (62) relative to the housing (12) along a second direction opposite the first direction.
