Arcusaflex couplings are a type of flexible coupling commonly used in marine
propulsion systems
to connect the ship's engine to the propeller shaft. These couplings are
designed to transmit
torque between the engine and the shaft while compensating for
misalignment, torsional
vibrations, and shock loads. Arcusaflex couplings are manufactured by
the company Vulkan Group,
a leading provider of flexible couplings and other marine propulsion
system components.
