A torque converter includes two differentials, the cage of the first differential receiving the input shaft power and the cage of the second differential driving the power-receiving output shaft. Both differentials have their planet wheels coupled by pairs, the first group constituting a gear train providing a ratio M while the second group constitutes a gear train providing a ratio N, the ratio M/N differing from unity. The converter input shaft is rigid with the first planet carrier while the output shaft is rigid with the second planet carrier cage.
