The couplings on the steering shaft serve to isolate the steering wheel from road noise and shock. Which option best describes this function?

Isolating the steering wheel from road disturbances is the main role of steering shaft couplings. These flexible joints allow small angular and axial movement in the steering column and absorb torsional vibrations as the road surface, engine movement, and chassis flex transfer forces. By damping and decoupling these inputs, the coupling keeps road noise and shocks from being directly felt through the steering wheel, improving ride comfort and steering feel. The shaft still transmits torque to the steering gear, but the primary function here is vibration isolation, not increasing steering effort or deliberately reducing feedback.
