FLEXIBLE SHAFT COUPLINGS This shaft coupling connects two shafts to transmit torque, motion etc. It is a coupling which can adjust itself to misalignment of two shaft connected by it. Misalignment may be angular, parallel or skew. When motion transmission is important, the misalignment should not affect the velocity and acceleration of the shaft. This calls for a torsionally rigid, yet flexible coupling. This coupling offer you this advantage using special design.
