Only if you choose to entirely ignore the effects of the rotational refrence frame. When you compare voltage to RPM you are silently multiplying by the demsionless unit radians.
More percisely, a flywheel stores power delivered to it torsionally, a spring (I assume you were talking about a linear spring) stores force applied to it in a constant direction (work) as energy.
Linear force ought to be thought of as DC, and torsional force, AC. An ideal capacitor will store energy (much like a Hookian spring) when a constant voltage DC (force) is applied to it. An inductor will store energy in the presesence of an AC source. (It is, of course, much more complicated then that, there are edge cases in which the difference between AC and DC is dificult to discern, such as wires long enough for the speed of electrical impulse to become meaningful, cases of magnetic resonance(ie transformers) etc.)
Flywheels look like capacitors, look like springs, look like inductors etc. because the nature of force and energy is reletavely constant. However when one uses vectors rather than scalers, it becomes clear that capacitors are springs, but not flywheels, and that inductors are flywheels, and not springs.
