Full Title

Full titles differ between systems:

IPC:

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > in which a fluid is used > with a coupling element in the form of a pneumatic tube

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) > in which a fluid is used (fluid couplings allowing continuous slip F16D31/00 - F16D35/00) > with a coupling element in the form of a pneumatic tube (similar clutches F16D25/04)
