1. An electromechanical brake system, comprising:
a brake actuator having a power transmission for transmitting an actuating force to a brake pad, said power transmission including a rotatable shaft;
a coupler with a locking element, wherein the coupler is controllable so that the locking element is engaged with the rotatable shaft and blocks rotation of the rotatable shaft or so that the locking element is disengaged from the rotatable shaft so that the rotatable shaft is rotatable;
a first receptacle into which a first tool is insertable so as to engage with the rotatable shaft and transmit a rotation on the rotatable shaft; and
a second receptacle into which a second tool is insertable so as to engage with the locking element and disengage the locking element from the rotatable shaft.
