The measurement of 
from event shapes with the DELPHI detector at the highest LEP energies
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.
