^{Flexible coupling types}

• Gear coupling. Gear Couplings are usually torsionally rigid couplings. These can transmit the highest amount of torque from one end to the other end.
• Old-ham coupling. Old-ham coupling usually provides a huge amount of parallel misalignment. It consists of three members.
• Disc Coupling. The disc coupling is having a thin sheet of discs laminated as the main part of the coupling for the flexibility to accommodate the misalignments.
• Grid Couplings. Grid couplings are very good at dampening the vibrations. These Grid couplings have some quite similar components as the gear couplings except the gear meshing. ...
Diaphragm coupling. Diaphragm coupling also uses thin sheets as a flexible element as like the disc coupling. ...
Fluid Couplings. The fluid coupling also is known as the hydraulic couplings. There will be two turbines (Impellers) covered by housing to fill the fluid.
Torsional couplings. Torsional couplings are mostly to accommodate the torsional vibration. Most of these are rubber coupling where it can dampen the vibrations and also accommodate the misalignments.
Bushed pin type coupling. It is a simple type of coupling with two flanges bolted with the help bolt and nut covered by bush made up of rubber.
Universal coupling. Mostly known as the Universal joint and it is well known to us. It is a linkage consisting of two yokes connected by a spider.
