Wankel Rotary Engine 

An ingenious engine design which avoids the reciprocal motion of the piston engine and manages to incorporate the suck, squeeze, bang, blow of internal combustion engines into a rotating piston.

Not a torture device of any kind.

The Wankel rotary engine is far more efficient than the latest hybrid cars, but nobody will buy one because it sounds too much like "wanker".

A torture device once used as a punishment for those who have commited a crime. It fits onto one's penis or vagina, and then is twisted, via a motor, to violently to cause aggonizing pain.

It's a torture device, does it really need an example?
