What is a safety coupling?

In drive technology, the safety coupling is a machine element that reliably transmits torques and limits them to a defined value.
Synonyms for safety clutches are overload clutches and disengaging clutches, in technical circles the term torque limiter is often used.
In addition to torque-limiting couplings, there are also force-limiting overload couplings on the market.
The term safety coupling is also used in fluid power engineering. Hydraulics engineers, pneumatics engineers, etc. understand this to mean couplings for the safe connection of hose lines.
