A breaker device (1) for acting onto a closure element (40) of a medical tubing (4) comprises a drive arrangement (2) having an electric drive device (20) and a drive element (23) driven by the drive device (20), and a breaker module (3) which is arrangeable on the drive arrangement (2). The breaker module (3) comprises a housing (30), a movable part (31) movably arranged on the housing (30) and a breaking element (315) for acting onto the closure element (40) of the tubing (4), wherein the breaker module (3) in an attached state is placed on the drive arrangement (2), the drive element (23) being in operative connection with the movable part (31) in the attached state such that a movement of the drive element (23) causes the movable part (31) to move for actuating the breaking element (315). A control device (5) serves for controlling the electric drive device (20) for driving the drive element (23). Herein, the control device (5) is constituted to control, during a detection routine, the electric drive device (20) to drive the drive element (23) in order to move the movable part (31), wherein the control device (5) is further constituted to analyse at least one feedback signal received during the detection routine for determining a type of the breaker module (3), the feedback signal being indicative of a movement of the movable part (31) during the detection routine.La présente invention concerne un dispositif de coupure pour agir sur un élément de fermeture (40) d'une tubulure médicale (4) comprenant : un système d'entraînement (2) ayant un dispositif d'entraînement électrique (20), un élément d'entraînement (23) entraîné par le dispositif d'entraînement (20), et un module de coupure (3) qui est apte à être fixé sur le système d'entraînement (2). Le module de coupure (3) comprend un boîtier (30), une partie mobile (31) agencée de manière à pouvoir être déplacée sur le boîtier (30) et un élément de coupure (315) pour agir sur l'élément de fermeture (40) de la tubu
