A device for checking the fitting of a threaded cap onto a container is associated with automatic cap-fitting apparatus, particularly of the carousel type, which includes a rotatable platform which can move at least one container about a principal axis of the apparatus and at least one screwing head for screwing a cap onto a respective container so as to close the container as a result of its movement about the principal axis. Each screwing head is arranged to screw a cap onto a container with a predetermined tightening torque. The device comprises a sensor unit for identifying a moment at which each screwing head reaches the predetermined tightening torque, a sensor unit for detecting the angular position of each screwing head relative to the principal axis, at which the predetermined tightening torque is reached by the respective head, the two sensor units being connected to one another in order to provide an indication that the predetermined tightening torque has or has not been reached by a screwing head within a predefined angular interval of the movement of the screwing head relative to the principal axis of the apparatus.
