Device for controlling the closing sequence of a leaf that opens second (fixed leaf) and a leaf that opens first (moving leaf) of a double-leaf door, • comprising a moving-leaf closing device by means of which the moving leaf can be moved from the opened state in a closing direction into the closed state, • comprising a fixed-leaf closing device by means of which the fixed leaf can be moved from the opened state in a closing direction into the closed state, • comprising a switchable locking device for the moving leaf, which can be switched to a locking state and to a release state, the locking device switched into the locking state locking the opened moving leaf against a movement produced by the moving-leaf closing device in the closing direction and the locking device switched into the release state releasing the opened moving leaf for a movement produced by the moving-leaf closing device in the closing direction, and • comprising a switching device by means of which the locking device for the moving leaf can be switched from the locking state into the release state as a result of the fixed leaf moving in the closing direction, and which switching device comprises a detection lever that extends in the transverse direction relative to the main plane of the fixed leaf for detecting the opening angle of the fixed leaf, which detection lever is attached to a switching shaft extending perpendicularly thereto and can be rotated in conjunction with the switching shaft about a shaft axis that extends in parallel with the main plane of the fixed leaf, the detection lever being rotated about the shaft axis into an awaiting rotational position and the switching shaft being rotated into an initial rotational switching position when the fixed leaf is open, the detection lever protruding towards the fixed leaf in the awaiting rotational position and being able to be acted upon as a result of the fixed leaf moving in the closing direction, and thereby being rotatable about the shaft axis from the awaiting rotational position into a closed rotational position assigned to the closed position of the fixed leaf, the switching shaft being rotatable in a rotational switching movement about the shaft axis from the initial rotational switching position to an end rotational switching position in conjunction with the detection lever that is rotated from the awaiting rotational position into the closed rotational position, the locking device for the moving leaf being switchable from the locking state into the release state owing to a rotational switching movement of the switching shaft over a rotational release angle and the detection lever being rotationally adjustable about the shaft axis relative to the switching shaft, characterised in that a torque-switching coupling is provided between the switching shaft and the detection lever, by means of which the detection lever is rotationally adjustable about the shaft axis relative to the switching shaft owing to a defined switching torque. • comprising a moving-leaf closing device by means of which the moving leaf can be moved from the opened state in a closing direction into the
