Abstract:
1. A coupling element for connecting an electrical actuator to a valve for controlling the operation of a radiator, the coupling element comprising: a first interface adapted to mechanically connect the coupling element to the electrical actuator; a second interface adapted to mechanically connect the coupling element to the valve; and a deformable portion, 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, upraised from a side wall of the coupling element and adapted to permanently engage with an annular groove formed at the electrical actuator such that the coupling element and the electrical actuator are connected with each other in a non-detachable but rotatable manner.
