The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects.[1] Couplings do not normally allow disconnection of shafts during operation, however there are torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost. In this coupling, the muff or sleeve is made into two halves parts of the cast iron and they are joined by means of mild steel studs or bolts. The advantages of this coupling is that assembling or disassembling of the coupling is possible without changing the position of the shaft. This coupling is used for heavy power transmission at moderate speed. They are used in installations where the systems requires a high level of torsional flexibility and misalignment capacity.This type of coupling provides an effective damping of torsional vibrations, and high displacement capacity, which protects the drive. The design of the highly flexible elastic couplings makes assembly easier. These couplings also compensate shaft displacements (radial, axial and angular) and the torque is transmitted in shear.[4] Depending on the size and stiffness of the coupling, the flexible part may be single and/or multi row.
