A thrust plate assembly having a housing which can be fastened to a flywheel for common rotation about an axis of rotation. A pressure plate is axially displaceable in the housing and is fixed with respect to rotation relative to the housing and is pressed in the direction of the flywheel by an energy accumulator. A wear adjustment device, with at least one adjustment element which is pretensioned in a wear adjustment direction, is arranged in the support path of the energy accumulator. Further, at least one play sensor arrangement is provided for detecting wear occurring during operation. The at least one play sensor arrangement has a locking element with a counter-engagement formation engaging with the engagement formation at the at least one adjustment element. Further, the locking element has a locking engagement formation which engages or is engageable in a detachable manner with a counter-locking engagement formation, the latter preferably being stationary with respect to the pressure plate. The locking element can be moved by a wear detection element and, in this way, the engagement between the locking engagement formation and the counter-locking engagement formation can be canceled.
