Hadronic event shape distributions are determined from data in e + e - collisions between 183 and 207 GeV. From these the strong coupling is extracted in , NLLA and matched + NLLA theory. Hadronisation corrections evaluated with fragmentation model generators as well as an analytical power ansatz are applied. Comparing these measurements to those obtained at and around M Z allows a combined measurement of from all DELPHI data and a test of the energy dependence of the strong coupling.
