    Abstract: A linkage for force transmission between a driven axle of a door actuator and an assembly surface, includes a hinge, a fastening arrangement designed for fastening the hinge to the assembly surface, in particular a door, frame or wall, wherein an assembly axis is defined perpendicularly to the assembly surface, and a lever arrangement which is fastened to the hinge so as to be rotatable about a hinge axis perpendicular to the assembly axis and which is designed for rotationally-fixed connection to the driven axle of the door actuator. The linkage is designed to detach through the weight of the door actuator falling down in the event of a fire and/or wherein the linkage includes a thermally activatable trigger element that is designed to detach the linkage in the event of thermal activation triggered by a fire.
