Abstract
A linear actuator () comprising a first part () and a second part () is disclosed. The first part () is arranged to rotate along with a rotating part () of a motor (), and the second part () is arranged to drive an actuated part (). A coupling () interconnects the first part () and the second part () to allow the second part () to rotate along with the first part () at the same angular velocity as the first part (). The coupling () defines a fit tolerance between the first part () and the second part () allowing the first part () to rotate a predefined distance before engaging the second part () and rotating the second part () along with the first part (). The fit tolerance ensures that the first part () reaches a certain angular velocity and thereby that the resulting torque transfer from the first part () to the second part () is sufficient, e.g. to release the actuated part () from a pre-tensioned state.
