shaped as an elastic ring centered on the axis, surrounding a portion of one coupling part and surrounded by a sleeve of the other coupling part

Full Title

Full titles differ between systems:

IPC:

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > with the coupling parts connected by one or more intermediate members > shaped as an elastic ring centered on the axis, surrounding a portion of one coupling part and surrounded by a sleeve of the other coupling part

CPC:

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > with the coupling parts connected by one or more intermediate members (F16D3/16 takes precedence) > shaped as an elastic ring centered on the axis, surrounding a portion of one coupling part and surrounded by a sleeve of the other coupling part

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
