An actuator device (1) comprising an actuator housing (2) with a fitting (4) for connecting the actuator (1) to an object (6), a motor (28) which via transmission elements (30, 32, 38, 40) drives an output actuator shaft (12) of the actuator (1), where the actuator shaft (12) is rotationally disconnectable from the motor (28), the actuator shaft (12) being rotatable between two angular positions where the one angular position may correspond to the object (6) being in a first condition and the other angular position may correspond to the object (6) being in a second condition, and where the actuator (1) is provided with an element (14) for storage of mechanical energy, the element (14) by energy cut-off to the actuator (1) being releasably arranged to be able to displace a nut (44) being prevented from rotating around its longitudinal axis, along a screw thread (42) complementary fitting to the nut (44), and connected to the actuator shaft (12), whereby the actuator shaft (12) is rotated between the two angular positions. |
