The connection device comprises a viscous coupling including a drive-side element with a work chamber and a reserve chamber in which the filling level ratios of viscous fluid in the chambers are controlled in accordance with preset values from the control device. In addition, the connection device also includes a belt disposed about the drive-side element and driven by the driving means so as to rotate the drive-side element. A driven-side element operatively connected to said drive-side element by the work chamber and in transmitting connection with an input element of the cooling compressor.
