We report on ferromagnetic resonance and torque curves measurements in electrodeposited CoPd alloy films with composition ranged from Co_{13}Pd_{87} to Co_{45}Pd_{55}. We show that the origin of the multimode structure of ferromagnetic resonance spectra in these strongly magnetostrictive polycrystalline films can be satisfactorily explained on the basis of the independent-grain-approach for a textured microstructure. The fourfold periodicity of the torque curves for the compositional range of 30-35 at% of Co seems to be originated by the microstructure features which lead to a distribution of the easy axis directions within the films.
