Some of the important features of flexible shaft coupling are,

1. Helical cut makes them behave like a springy in the X Y and Z linear axis but not in the rotational axis. That means that you won’t get more backlash, hence they are suitable for precision CNC work.
2. A coupling is a device which transmits power and torque. 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 exceeds.
3. By careful selection, installation and maintenance of couplings, substantial savings are possible in reduced maintenance costs and downtime.
4. It can protect the driving and driven shaft members against harmful effects because of misalignment of the shafts, sudden shock loads, shaft expansion or vibrations etc.
