Abstract
A coupling device for driving an engraved cylinder of a printing device. The coupling device comprises a single part of chromium, nickel and molybdenum alloyed steel having undergone core hardening. The coupling device includes a central cylindrical portions, first and second flanges at the respective first and second ends of the cylindrical portion, each flange having a side portion operable to distort under stress and act as a membrane. The ratio of the difference between the diameter and the flange and the diameter of the central portion divided by the average thickness of the side portion of the flange is between 7 and 15.
