A fluid coupling is a hydrodynamic device used to transmit rotating mechanical power. It has been used in automobile transmissions as an alternative to a mechanical clutch. It also has widespread application in marine and industrial machine drives, where variable speed operation and/or controlled start-up without shock loading of the power transmission system is essential. They are also sometimes called a Fluid Flywheel.
yes,i think so.
i don't know actually
It is a fluid coupling using a viscous (thicker type) fluid, similar to the coupling between the drive and driven impeller of an automatic transmission in a car.
Breather is provided where the oil tends to give out fumes after getting heated. in a fluid coupling the fluid is not heated upto that temperature hence not required
resilient plate is used to protect fluid coupling from damages and takes the overload acting on the device ,
They are of similar design, but a fluid coupling simply transmits torque (with some frictional loss), while a torque converter amplifies torque, similar to a reduction gear.
Scoop coupling is nothing but a fluid coupling works based on the hydro dynamic principle. Scooping is the collecting the oil from the working chamber(space between pump wheel and turbine wheel) which will effects the transmission.

Difference in output speed from input speed is known as slip.

There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
