Torsion balance is a very very sensitive device used to measure very feeble forces.
Coulomb himself invented a torsion balance and came up with what we know was "Coulomb's law". He also used it to discover the inverse square forces between magnetic poles.
A torsion balance was used later by Cavendish to verify Newton's Law of Gravitation.
