Coupling element and coupling assembly for axial torque transmission, and disc assembly therefor

A coupling element for axial torque transmission, said coupling element comprising:

• at least one first connection element and one second connection element for connecting rotatable machine parts;
• an axially interposed resilient disc assembly alternately connected to the first connection element and the second connection element, so that the connection elements are connected to each other in a torsionally rigid but axially and angularly moveable manner, wherein the disc assembly is composed of a plurality of resilient discs;
• a slotted centering sleeve insertable while establishing elastic interlocking engagement and/or preferably elastic play in complementary holes in one of the two connection elements and in the disc assembly while pre-centering the one of the two connection elements relative to the disc assembly and while pre-centering the individual discs relative to each other;
• and
• a threaded centering bolt or threaded into the slotted centering sleeve while fixing and centering the one of the two connection elements relative to the disc assembly.
