A coupling element has a first interface, which is adapted to mechanically connect the coupling element to an actuator, a second interface, which is adapted to mechanically connect the coupling element to a valve, and a deformable portion, which is shaped in such a manner, that, as a result of a compression along an axial direction of the coupling element, the deformable portion irreversibly bends such that a projection is formed. Thereby, the projection is adapted to permanently engage with an annular groove formed at the actuator, such that the coupling element and the actuator are connected with each other in a non-detachable but rotatable manner.
