Coupling a modular construction and method of assembling the same

Coupling the modular design, comprising: - a flywheel (1), of which a first end is connected to a corresponding part of an engine for power transmission; - a coupling cap formation (2) arranged with a corresponding cylindrical surface (1a) of the flywheel (1) surrounding and in this assembled clutch cover (10, 30) and with a pressure plate (12) coaxial with the flywheel (1) and a facing the same second end face opposite to the first force-receiving end surface; - one with the platen (12) and the flywheel (1) coaxial and arranged between said clutch disk formation (3); and - a ring gear (6) fixed to a peripheral surface (10a, 30a) of the clutch cover (10, 30) is mounted, characterized, that the ring gear (6) in the region of the cylindrical surface (1a) of the flywheel (1) radially on the outside of the multi-axial slotted peripheral surface of the clutch cover (10, 30) is shrunk and thereby the clutch cover (10, 30) on the cylinder-shaped .. ,
