Abstract: An electromechanical door lock actuation device with an actuator module is mounted on a metal profile of a glass door such that the actuator module is offset from the door lock in order for the actuator module to not block opening of the door.

Abstract: An electromechanical door lock actuation device with a motor for rotation of a connector-receiver that has two jaws for gripping a door knob or key when the device is installed on a door blade, wherein the width between the jaws is adjustable for a tight fit against the knob or key.

Abstract: A door lock actuation device configured for operating a door lock in a door blade, wherein the door lock includes a dead bolt driven by rotation of a connector is provided. The device includes a casing, inside which there is provided a motor for driving a rotational connector-receiver that receives and rotates the connector. The device also includes a rotational handle mechanically connected to the connector-receiver, for forcing rotation of the connector-receiver by manual rotation of the handle. The motor is selectively disconnectable from the connector-receiver for manual driving of the connector-receiver by the handle without backdriving the motor.
