An air compressor is being refitted in the engine room. The compressor and motor are coupled using a flexible coupling and are mounted on a common 'skid' which fixed to the deck with resilient mountings. Which of the statements, from the options given, relating to the alignment of the motor and compressor is true?

As long as the two coupling halves are at the same height the flexible coupling will accommodate any horizontal misalignment or difference in the gap between the coupling faces.
