Clutches are used to control power transmission. When they receive a redstone signal they will transmit all input power unchanged, but will not transmit any power if not supplied with a redstone signal.
Rotarycraft Handbook DescriptionEdit
"The clutch is basically a gated shaft - when powered by redstone, it transmits its input torque and speed unchanged. Unpower it, and it outputs nothing."
