Abstract / Description:We report results on measurements of the strong coupling aS from event shape data at PETRA and LEP. Their distributions are analysed employing the new NLLO+NLLA calculations and
hadronisation correction by Monte Carlo models using JADE data. This results in a very precise measurement of the strong coupling, alpha_S(MZ) = 0.1172±0.0051. The running of the strong coupling is confirmed significantly. Analyses of their moments using next to leading order calculations
and hadronisation correction by analytical power corrections show shortcomings of the calculations, which can be expected to be alleviated by the NNLO calculations.
