jaw and spider
splined and rubber
pin and disc
pin and rubber

Question 17

material and mechanically flexible coupling with steel spring grid that allows for torsional flexibility and minor amounts of misalignment

Answer 17

steel grid coupling

Question 18

material and mechanically flexible coupling torque passed through spider and spider insert acts as a dampener reducing shock and vibration
