Full Title
Full titles differ between systems:
Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > adapted to specific functions > specially adapted for accumulation of energy to absorb shocks or vibration
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) > adapted to specific functions > specially adapted for accumulation of energy to absorb shocks or vibration (by making use of fluid elements F16D3/80)
No child classifications to compare. This is a leaf node in both IPC and CPC.
