Precise measurements of top quark couplings are presented. The measurements cover the single top tW cross section, the measurement of the top-quark branching-fraction ratio R=B(t → Wb)/B(t → Wq) and the CKM matrix element V tb from the single top cross sections. Top quark polarisation in the t-channel single-top quark production and dilepton tt, and W-helicity fraction measurements along with searches of top quark anomalous couplings in lepton plus jet channel are also presented.
