  The explicit form of linearized gauge invariant interactions of scalar and
general higher even spin fields in the $AdS_{D}$ space is obtained. In the case
of general spin $\ell$ a generalized 'Weyl' transformation is proposed and the
corresponding 'Weyl' invariant action is constructed. In both cases the
invariant actions of the interacting higher even spin gauge field and the
scalar field include the whole tower of invariant actions for couplings of the
same scalar with all gauge fields of smaller even spin. For the particular
value of $\ell=4$ all results are in exact agreement with hep-th/0403241
